Job Details

L3 Support Engineer for a major retail client, offering up to 143,000 RUB net. Responsibilities include deep Root Cause Analysis, bug localization, and preparing cases for developers. Requires expertise in MySQL, Redis, Kubectl, and Grafana.

We are looking for an expert to become the 'last instance' in the support chain. Your task is not just to close tickets, but to conduct deep Root Cause Analysis (RCA), localize complex bugs, and prepare a knowledge base for developers. L1 and L2 are already in place, so the most hardcore tasks are for you. What you will do: • Work with data: execute complex SELECT queries and data dumps upon business requests. • Entity management: make direct changes in the database via Workbench or scripts (strictly according to instructions). • Deep Debugging: localize and reproduce bugs, find root causes of system failures. • Knowledge transfer: create detailed instructions for L2 colleagues to reduce the load on the expert line. • Interaction: prepare 'clean' cases for transfer to development or vendors.

Our expectations (stack): • MySQL: confident SQL query writing and experience with Workbench. • Redis: understanding of principles of operation and interaction with cache. • Kubectl: basic skills in working with K8s (viewing logs, pod status). • Monitoring: fluent in Grafana and LogQL for anomaly detection.
